... ) and depressurization contributed to the CO 2 breakout from the water which caused severe corrosion with the protective siderite readily removed. Corrosion occurring at CO 2 gas/water/metal boundaries resulted in high pitting rates and corrosion was aggravated with the increase in mass transfer when gas bubbles...

... as a demonstration by the U.S. Navy. The present work studies corrosion of plain-carbon steel (UNS G10180 (1) ) in natural seawater/fuel mixtures of F-76, HRD-76, and a 50%-50% blend of F-76 and HRD-76 (50-50 blend). Severe corrosion occurred on steel immersed in the seawater layer with the outer rust layer...

... gas loading - when one train is shutdown is 0.45 mole H2S/mole MEA. Acid gas loading - in lean amine after regeneration is 0.06 mole H2S/mole MEA. To understand the reasons for severe corrosion that was taking place, the following data for refinery ARU unit (3 trains) were collected from Year 2001...

... September 2004. In the original exchanger, prior to the revamp, no significant corrosion of tube bundle or other components had occurred. No tube bundle replacement was needed within the 14 years of operation. However, after revamp in 2004, severe corrosion and damage was noticed, mainly on the shell side...

... ABSTRACT Epoxy coated reinforcement (ECR) has been used in Florida from the 1970s to 1990s but has been discontinued due to the observation of severe corrosion in some ECR bridges after short service times. Corrosion projections have been made in earlier investigations based on corrosion...

... corrosion. The identification of lines likely to have severe corrosion is made by first modeling each line to find the point of highest likely corrosion severity using a measurement that is proportional to percentage rate of wall loss termed likely corrosion severity score . Assuming that all relevant...

... have shown that severe corrosion occurred in the presence of a 50 wt.% ZnC12-50wt.% KC1salt mixture in the temperature range from 300 to 500 ?C. The corrosion products on 2.25Cr-lMo were found to be Zn-rich iron-oxide precipitates in contact with the gas phase and a Fe203 layer underneath. In contact...

... on the applicability and limitations of epoxy-coated rebars in similar service. Severe corrosion of epoxy-coated reinforcing steel was documented at major construction projects in a subtropical marine environment. The corrosion was caused by the combined effect of several factors. These included two primary factors...
